On Saturday, thousands of people took to the streets in the US, Canada and worldwide to protest the lack of gun restrictions that led to the deadly shooting in Parkland, Florida earlier this year. The main march took place in Washington, DC, where a reported 850,000 people lined the streets (which yes, was much bigger than President Trump’s inauguration). Hundreds of smaller marches popped up across North America, from Toronto to Alaska, with some of the biggest marches taking place in New York and Los Angeles.

Saturday’s marches had no shortage of moving moments, but it also had no shortage of inspiring and heartbreaking signs. Here are just a few of the best.

Peanut allergies are serious, but this is a great point.

Sometimes kids get to swear.

Excellent point.

We’re pretty sure God isn’t down with guns in school.

Simple and powerful.

Sad, but true.

A number of celebs also joined in on Saturday’s march, with Paul McCartney marching in New York, telling CNN that “One of my best friends was killed in gun violence, right around here, so it’s important to me.” The founding Beatle gave the interview only a few blocks away from the Manhattan apartment building where John Lennon was fatally gunned down in 1980.
